Zero‑Exposure SMTP Mail Sender (MGC Secure Edition)

A secure SMTP email‑sending MCP server that prevents credential exposure by using MGC Blackbox for local encrypted storage.
Your AI can send emails — but never sees your SMTP password.

✨ Features

• Zero‑Exposure: SMTP password never leaves your machine
• Local encryption: Powered by MGC Blackbox secure vault
• Safe for AI automation: Credentials are never passed to the model
• Simple API: One MCP tool — send_email
• Compatible with all SMTP providers

🛠 MCP Tool: send_email

This MCP server exposes one tool:

send_email

📤 Example (Python)

from mcp import MCPClient

client = MCPClient("http://localhost:57219")

client.call_tool("send_email", {
    "to": "to@example.com",
    "subject": "Hello",
    "body": "This is a secure email.",
    "info_type": "config",
    "info_owner": "your_email"
})

💬 Trigger Phrases (for AI clients)

• “send an email”
• “send via SMTP”
• “email this to someone”
